Physics 6820 -- General Relativity


This course is an introduction to general relativity, aimed at advanced undergraduates and beginning graduate students. Standard undergraduate coursework (including mechanics, special relativity, multivariable calculus, and linear algebra) will be assumed as background. I will not assume you have had any prior exposure to tensor calculus or curved manifolds; the first part of the course will introduce this material.

The course will meet Wednesdays and Fridays, 12:40-2:45 PM, in Smith Lab 1094. The first class will be held on Wednesday, August 21.

The main course text will be Bernard Schutz, A First Course in General Relativity.

Topics covered will include the following: (note I changed the ordering to follow the book)

Procedures

Homeworks will be due on Fridays. Office hours will be held on Thursdays, 11-12 and 4-5, in PRB M2010 (starting Aug. 30).

There will be an in-class midterms (1 hour) and a final exam. Please contact the professor if you require alternate arrangements for either or both exams.

Grading will be based on the homework (75%), midterm (10%), and final (15%).
